DESCRIPTION:
"For No One" is a song written by Paul McCartney (credited to Lennon/McCartney) that originally appeared on The Beatles' seventh album, Revolver. A baroque pop song about the end of a relationship, it was one of McCartney's most mature and poignant works upon its release. Mostly performed by the composer, the track is distinguished by its French horn solo, performed by Alan Civil and used as an obbligato in the final verse.
